I originally purchased this binder in a size M (i was between sizes) and it was too small so i put in a request to size up to an L. The exchange process was really simple and the person that emailed me was very helpful, giving resourses on how to use binders and tips and tricks, as well as clear instructions for the exchange! The binder is great quality and very comfortable and breathable and looks amazing, and it makes me feel very gender euphoric whilst wearing. It can be slightly difficult to get on and off the first couple times but ive worn it 3 or 4 and have had no troubles. As someone which struggles with clothes and sensory (I have autism and have struggled with other binders in the past due to the materials), this material is very smooth and stretches so it also is accessable that way too.
Overall, this binder gives amazing results, can be worn for a long time per day without discomfort, is breathable and the staff are really helpful. 10/10 would recommend :)
